Perhaps you should try some spelling variations:
doanh giai » doanh giao, doanh ngoai, doanh tai
doanh dai » doanh tai, doanh dao, doanh va
hieu van » hieu va, thien van, lieu va
sach kem » hanh kem
nam xuc » cam xuc, nam xua, nam thuc
xuc van » duc van, luc van, vuc van
cua te » cua tu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach kem) or (sach y)) nang x ho. hieu van nam xuc van ((doanh dai) OR (doanh giai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach kem) OR (sach y)) nang x ho. hieu van nam xuc van ((doanh dai) OR (doanh giai)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach kem) or (sach y)) nang x ho. hieu van nam xuc van ((doanh dai) OR (doanh giai)) cua te*".
